Abstract
Knockdown furniture comprising flat, interlocking, planar parts assembled or disassembled without tools or fasteners. A flat top is supported above ground. A plurality of identical, generally C-shaped legs operatively oriented in radially, spaced apart relation upon erection, support and elevate the top. Each leg comprises a foot touching the ground, an arm for grasping the top, and a wedging section of varying width that is oriented generally perpendicularly. A planar lock shaped like and parallel with the top engages the leg wedging regions. The legs penetrate slots defined in the lock and are thus captivated. Each leg intermediate section may vary in width, with the outside of each intermediate leg section comprising a ramp, and the inside forming a complementary leg edge. The wedging action resulting from slot-to-ramp engagement locks the parts together, with the complimentary leg edges firmly abutting one another.
Description
BACKGROUND OF THE INVENTION
I. Field of the Invention
The present invention relates generally to modular furniture items. More particularly, my invention relates to portable, knockdown furniture items comprising a plurality of flat, readily transportable parts that can be easily erected or disassembled without special tools.
II. Description of the Prior Art
The prior art recognizes that modular, knockdown furniture items have a variety of useful applications. One advantage of modular construction is that the device parts may be shipped in a flat configuration in disassembled form. The user can then simply fit the parts together to create a piece of furniture. With a variety of parts of different shapes and sizes, the user can create different artistic effects as well as different furniture forms. Once at the application site, the parts should fit together reliably and easily to facilitate erection.
Furniture articles that can be folded or disassembled into individual, flat constituent parts can more easily be stored and transported. When unassembled and piled together, flat parts will occupy a minimum amount of storage space. Hunters, campers, and other outdoor users, for example, prefer knockdown items, as they can easily be stored, hauled to the camp site, and erected for use in a shot period of time. The user can easily put the items together, as long as simplicity of design is maintained, and especially where the design omits irregular or complex parts. Favorable designs should comprise parts that may be quickly and easily assembled without the use of hand tools. The requirement of special tools is especially disadvantageous. Furniture items comprising a minimum of parts that fit together reliably without the necessity to read or study manuals or other documentation are preferred.
One problem with modular furniture is that sturdy, assembled structures are difficult to erect with parts that are easily assembled and disassembled. Some prior art knockdown articles have recognizable disadvantages. Some devices comprise too many parts, and sometimes tools or special fasteners are required for erection. Some knockdown devices comprise intricate parts that are too expensive. Some folding furniture devices require assembly by relatively skilled personnel. Some knockdown articles cannot withstand heavy use, and they will not reliably support heavy loads. Known devices that do not require fasteners and/or hand tools for assembly or disassembly lack the mechanical durability and dependability required for commercial success.
The most reliable and durable prior art knockdown furniture items have all required tools or multiple fasteners. An easily assembled knockdown arrangement that consists only of flat pieces, and which can be hand-assembled into a durable and powerful furniture article would be highly desirable.
SUMMARY OF THE INVENTION
All embodiments of my knockdown furniture comprise a plurality of flat, planar parts that can be easily erected without hand tools or fasteners. The assembled items are easily disassembled, and the light-weight, flat parts can be quickly separated and stored for transportation.
Each furniture item comprises a plurality of identical, generally C-shaped legs, a relatively large, flat top supported by the legs, and a planar lock in the form of an intermediate surface disposed by the legs below the top. The top may be circular, or it may be in the form of a regular polygon. The lock may be shaped similarly, but preferably it is smaller than the top. Each leg is generally C-shaped, comprising a foot for touching the ground or floor, an upper arm for grasping the top, and an intermediate section that is oriented generally perpendicularly relative to ground when assembly is completed.
Special slots are defined in the lock for receiving the legs, which are first rotated during assembly until the legs are vertical, with their midsections confined and captivated within the lock slots. Importantly, each leg intermediate section varies in width. The outside of the leg intermediate region comprises a ramp. The inside of the same area forms a complementary leg edge. The distance between the ramps structure and the complimentary edges varies, to enable a wedging action in response to the lock. The legs assume a position in assembly wherein they are radially spaced apart, with the inner, complementary leg edges of each leg midsection abutting one another. At the same time, the leg's ramps contact the outermost ends of the lock slots, in which the legs are inserted and confined. Once the legs are installed, the lock can be pressed downwardly to firmly, compressively secure the legs and the rest of the parts together. The leg arms have hooks that firmly grasp the top in assembly.
This invention provides a knock down furniture design comprising a plurality of flat, planar parts that can be fitted together without tools or fasteners. Once assembled the device functions durably and dependably until dissembled as desired.
Thus a basic object of my invention is to provide a knockdown furniture item comprised only of flat, interfitting parts that can assembled without tools or fasteners.
Another basic object is to provide a robust furniture item that can be easily stored and transported.
A fundamental object is to provide a furniture item of the character described that can be user-erected without tools.
Similarly, it is a broad object of my invention to provide a knockdown furniture item comprising a minimal number of parts.
Yet another important object is to provide a furniture item of the character described that can be deployed in the form of a table, chair or other desired furniture article.
Another object is to provide a stool, table or similar furniture article that can be stored in a completely flat orientation.
A similar object is to minimize stowage and transportation volume requirements.
Another important object is to provide a similar furniture article of the character described which is lightweight and sturdy.
A still further object is to provide a modular knockdown furniture item such as a table or chair whose components can be sold in kit form easy assembly.
Yet another broad object is to provide an article of furniture comprising generally planar parts that are made of sheet or board material.
Another important object is to enable the user to quickly erect a durable and sturdy furniture article without special training.
A similar object is to enable the user to quickly erect a sturdy and durable furniture item without the need for referencing complex manuals or instructions.
A fundamental object is to provide a modular, knockdown furniture construction of the character described comprised of parts that may be manufactured from plastic, corrugated material, cardboard, plywood or the like.
These and other objects and advantages of the present invention, along with features of novelty appurtenant thereto, will appear or become apparent in the course of the following descriptive sections.

DETAILED DESCRIPTION
Turning initially now
FIGS. 1-12
to the drawings, a preferred embodiment of my knockdown furniture invention comprises a table, generally designated by the reference numeral
30
. Table
30
comprises a plurality of planar parts to be described later, that can all be made from planar material such as cardboard, fiber board, corrugated, plywood or the like. The parts may be assembled or disassembled, as described later, without hand tools, and when assembled, a rigid and dependable furniture item is created. No special fasteners are required.
Table
30
comprises the three main components laid out for convenient viewing in FIG.
9
. These are legs, generally designated by the reference numeral
32
, a planar, generally polygonal top, broadly designated by the reference numeral
34
, and an intermediate, planar lock, generally designated by the reference numeral
36
. When the foregoing parts are assembled, as described in further detail hereinafter, the legs are inserted through the slot structure
39
(
FIG. 4
) defined in the lock
36
, and they reach upwardly and engage and support top
34
. Once they are inserted and properly juxtapositioned by the assembler, the lock
36
is pressed downwardly to secure the legs in radially spaced-apart orientation, firmly grasping the top and reinforcing the leg structure. As hereinafter further described, the furniture item (i.e., table
30
) results. It is adapted to be deployed upon a firm, planar, supporting surface such as floor
37
(FIG.
1
). When assembled, the table legs
32
are firmly pressed against one another in an edgewise fashion, with the table top
34
is disposed vertically above the lock
36
. When properly deployed, lock
36
will be parallel with top
34
. The exposed, upper supporting surface
35
of table top
34
presents a strong and durable support for a variety of items, including picnic supplies, silverware, plates, pots and pans and the like.
In table embodiment
30
the top
34
is preferably octagonal, comprising eight symmetrical edges
40
(
FIG. 2
) that are radially spaced apart about the center of table surface
35
. This configuration is but one of many that may be adopted. For example, the top
34
may be round, triangular, hexagonal, or square. It may assume the shape of any regular polygon. Where legs of varying configurations are allowed, then the top may assume a rectangular shape, or even irregular shapes, resembling trapezoids, truncated cones, semicircles and/or the like. Preferably the legs form a symmetrically array, placed radially about the structure. Preferably there are a number of legs
32
at least equal to three, and preferably equal to an integer fraction of the number of top sides. For example, where an octagonal top
34
is chosen, eight table sides result, and eight divided by the integer two yields four legs. As will become apparent hereinafter, the number of legs could equal the number of table top sides, particularly with a square top. Preferably the design contemplates one leg
32
for each two table top sides.
The preferred legs
32
are all planar, and preferably, in a typical package of components sold as a kit for example, each leg is identical. With primary reference directed to
FIGS. 4
,
5
and
9
,
10
, the legs comprise a bottom foot
46
, an upper arm
50
, and an integral midsection
48
. Each foot
46
comprises a terminal bottom edge
49
(
FIG. 5
) adapted to be disposed upon a supporting surface
37
(
FIG. 1
) when the assembly is constructed. Foot
46
upwardly transitions to midsection
48
(FIG.
4
). The outer edge
51
(
FIG. 4
) of each foot meets the supporting ledge
52
(
FIGS. 4
,
5
) formed on the outside of midsection
48
. A step-like, stair-shaped wedging region
53
is formed on the outside of the legs, spaced apart from the specially configured, complimentary inner edges
54
(
FIG. 9
) of each midsection
48
. Importantly, the width of the leg across the intermediate portions
48
varies. In other words the distance between the inner edge
54
and the opposite, outer wedging region
53
preferably increases as one moves downwardly. As explained later, this facilitates a locking action as the lock is pressed into position.
Each arm
50
integrally extends angularly upwardly and outwardly from midsection
48
(i.e., FIG.
10
). The inner, upper arm edges
58
and
59
, and upper, supporting ledge
60
(
FIG. 8
) transition away from special edge
54
of the midsection
48
. The lower, outer edge
61
of the arms is substantially straight. As best seen in
FIG. 5
, the midsection's wedging region
53
comprises an angled edge
62
(
FIG. 5
) that adjoins arm upper edge
61
, and raised, projecting region
53
(FIG.
5
). Region
53
comprises a first ramp
67
(
FIG. 8
) and a second ramp
69
(FIG.
5
). Ramp
67
adjoins angled midsection edge
62
. Ramp
69
adjoins ramp
67
and ledge
52
(FIG.
5
). Region
53
effectively causes the width across the leg midsection to vary; i.e., the width between edges
54
and
62
is less than the width between edge
54
and ramps
67
or
69
. The lock wedges the parts together as it is pressed downwardly, with the leg midsection captivated within the lock slots described later. In other words, in assembly, with the legs juxtapositioned between the orientations of
FIGS. 5 and 10
.
FIG. 5
shows the lock partly installed upon the loose legs, and
FIG. 10
shows the firm, leg alignment maintained by the lock after it has been pressed into place.
The upper arm
50
of each leg
32
terminates in a generally C-shaped hook
70
(
FIGS. 5
,
8
,
10
) that projects from exposed ledge
60
of the arm. When assembled, the arm ledge
60
will support the table top
34
previously described, as the various table edges
40
can be fitted within channels
72
so the arms support the table top. The upper ledges
60
of the each leg are parallel with ledges
52
(
FIG. 4
) that support the lock
36
. Hook
70
comprises an inwardly projecting channel
72
that receives edges of the table top upon assembly. The channel
72
results from the generally C-shaped terminus
73
at the top of each leg's upper arms
50
. Channels
72
(
FIG. 8
) will be arranged symmetrically, in a radially spaced apart configuration conforming to the placement of the legs upon assembly. Upon proper assembly, the exposed upper surface
74
(
FIGS. 8
,
10
,
11
) of each terminus will be oriented parallel with ledges
52
and
60
previously described, with adjoining vertical surface
75
(
FIG. 10
) oriented perpendicularly.
The lock
36
is best addressed with concurrent reference to
FIGS. 4
,
9
,
11
, and
12
. It will be observed that the generally planar lock is flat and square. It's shape is not as important as the fact that it contains an internal, central slot structure
39
, which is symmetrical. With four legs, it is preferably in the form of a cross, with one individual slot to receive each leg. In this embodiment, four individual radially spaced apart slots
80
(
FIG. 4
) are defined in the lock
36
. The lock
36
has a plurality of symmetrical sides
81
(
FIG. 9
) forming, in this instance, a square shape. The shape can be different, as apparent to those with skill in the art. The number of slots preferably equals the number of legs to be used. In the best mode of this embodiment, the four, individual radially spaced-apart slots
80
meet at the center
82
of the lock, and the outermost slot ends project towards the lock corners. The slots are dimensioned carefully to frictionally and firmly receive and lock the legs. The distance from a slot end
83
to the slot center
82
(
FIG. 9
) roughly approximates the width of the leg midsection or wedging region as measured between inner edge
54
(i.e.,
FIGS. 4
,
5
,
9
) and the ramps
67
,
69
(
FIGS. 5
,
10
).
Proper dimensioning of the legs and the lock slots is important. As best seen in
FIGS. 11
,
12
, the leg midsection inner edges
54
are preferably stepped, comprising a notch
90
and a projection
91
. When the legs are compressed together in the assembled shape, the notch of one leg abuts the notch of the others, forming the arrangement of FIG.
12
. However, the inner edges of the legs could be designed differently. For example each could be shaped like a pointed arrow. Importantly, the critical fitting distance between one leg projection
91
(
FIG. 12
) and the outer end
83
of a corresponding slot has been designated by reference numeral
85
(FIG.
12
). This distance
85
is preferably equal to the width between inner edge
54
and ramp
69
.
The legs are thus bound together in frictional, compressive abutting relation as in
FIG. 12
, by compressive action of the lock
36
as it is pressed down over the legs during assembly. The variable width midsection region (i.e., the leg width between ramps
67
, and edge
54
) is captivated within lock slots of finite length; as the lock is pressed downwardly, with the legs properly oriented, action of the ramps
67
,
69
sliding against the outermost limits of the lock slots results in compression. The legs are compressed slightly, as they are firmly drawn together by the lock. At the same time, the inner edges
54
of each leg mutually abut one another (FIG.
12
). The various projections
91
(
FIG. 12
) abut in the mutually facing notches
90
to form a stable, radially interlocking structure. The compressed legs will remain stable in this radially interlocking arrangement, with predetermined compressive forces from the properly mounted lock
36
maintaining all the parts together.
Assembly:
Referring to
FIG. 9
, the flat pieces should be recognized, and laid out in a flat, symmetrical arrangement prior to assembly. A prudent assembler will be cognizant of the preferred, target configuration seen in FIG.
1
. As seen in
FIG. 6
, the arms
50
of each leg are first thrust into the various slots
80
of the planar lock
36
, and preferably, their generally radially spaced-apart target orientation is preserved. As the legs reach upwardly and are positioned vertically, their hooks
70
may engage the table top
34
. As the pertinent table top edges
40
are firmly received within the channels
72
(
FIG. 10
) alignment begins. The width of the leg's midsection between wedging region
53
(i.e., ramp edge
67
,
69
) and inner edge
54
increases from top to bottom. The legs may first be arranged in a generally radially spaced apart, vertical orientation as in FIG.
4
. Then the lock
36
is “installed.” Essentially, the legs are first thrust within the lock slots
80
and then rotated about their midsections to transform them between the orientations depicted in
FIGS. 5 and 10
. Once the legs are rotated to assume the desired orientation wherein they grasp top
34
, the lock
36
may be gently pressed downwardly, until resting upon ledges
52
(
FIG. 5
) and forming the stable assembly. This locks “wedges” the parts into position with its slot ends
83
(
FIG. 9
) being wedged against the ramping surfaces
69
(
FIG. 5
) defined in the leg midsections. Once the lock
36
is pressed downwardly until it firmly rests upon the previously described leg ledges
52
(FIG.
4
), assembly is completed, and the arrangement will remain stable and fixed.
First Alternative Embodiment:
An alternative embodiment (i.e., the second embodiment) seen in
FIGS. 13-21
of the drawings comprises a chair
130
. Alternatively it can be used as a stool, or a table or a shelf. Chair
130
comprises a plurality of legs
132
, a preferably circular top
134
, and a preferably circular lock
136
. In this embodiment, the lock is sized and configured somewhat like the top
134
. As before, when the aforementioned planar parts are correctly assembled, a strong and dependable structure results.
Each leg
132
(
FIG. 20
) is identical. With primary reference directed to
FIGS. 16
,
20
and
21
, the legs comprise a bottom foot
146
, an upper arm
150
, and an integral midsection
148
. As before, a step-like, stair-shaped wedging region
153
(
FIG. 21
) is formed in the midsection at the angular vertice formed by foot
146
and arm
150
. Each arm
150
integrally extends angularly upwardly and outwardly from each corresponding midsection
148
. An upper supporting ledge
160
supports the top
134
after assembly. The lower ledge
154
supports the lock
136
in the same manner as that previously described.
As best seen in
FIG. 21
, the leg midsection's all comprise a wedging region
153
having a pair of angled ramp portions that function as described previously when the legs are compressed within the locks slot structure
139
As before, each leg
132
terminates at its top in a generally C-shaped hook
170
that captivates the top
134
upon assembly. The lock's slot structure
139
, is symmetrical, in the form of a cross, and comprises four individual radially spaced apart slots
180
(
FIG. 21
) to fit the four legs. These slots are dimensioned carefully to frictionally and firmly receive and lock the legs as previously described. Assembly occurs as previously described.
Second Alternative Embodiment:
A third embodiment seen in
FIGS. 22-26
of the drawings comprises a table
200
which can also be used as a stool or shelf. Table
200
comprises a plurality of similar, flat legs
202
, a preferably circular top
204
, and a preferably circular lock
206
that has a smaller diameter than table top
204
. Of course top
204
and lock
206
can be shaped or dimensioned differently, as will be appreciated by those skilled in the art. In this embodiment, the lock is also sized and configured somewhat like the top
204
. Once again, when the aforementioned planar parts are correctly assembled, a strong and dependable structure results. However, the lock
206
is coupled to the legs through a different arrangement. While the indicated structure is slightly different, principles of operation remain largely the same.
Each identical leg
202
comprises a bottom foot
208
, an integral upper arm
210
, and an integral locking protrusion
212
. As with the prior embodiments, each leg
202
terminates at its top in a generally C-shaped hook
221
(
FIG. 26
) that captivates the top
204
upon assembly. Unlike prior embodiments, lock
206
is not penetrated by the arms of the legs, rather, it is fitted to the abutting protrusions
212
. Each protrusion
212
defines a step-like, stair-shaped wedging region
215
that tightly fits through slot structure
218
defined in lock
206
. Each arm
210
integrally extends angularly upwardly and outwardly from the corresponding protrusion
212
. An upper supporting ledge
220
on each arm
210
jointly supports the table top
204
after assembly. The lower ledge
230
supports the lock
206
in the same manner as that previously described.
As best seen in
FIG. 26
, the wedging region
215
comprises a straight, perpendicularly upwardly extending edge
222
defined on protrusion
212
that is spaced apart from and parallel with the legs elongated inner edge
225
. Inner edge
222
adjoins the upwardly extending, inclined protrusion edge
224
that functions as a ramp. Edge
224
extends upwardly to flat, protrusion top
226
. The spaced-apart arm
210
has an inclined upper edge
228
that extends angularly upwardly from the arm's lower vertical edge portion
229
(FIG.
26
). Arm vertical edge portion
229
is spaced apart from and parallel with protrusion edge
222
, with a flat, lower ledge
230
defined therebetween.
The lock's slot structure
218
(
FIG. 22
) is symmetrical, preferably in the form of a cross, for embodiments using four legs. There are four individual, radially spaced apart slots
234
(
FIG. 22
) to fit the four legs. These slots are dimensioned carefully to frictionally and firmly receive and lock the legs as previously described. They are dimensioned substantially the same as dimension
231
in
FIG. 26
so that firm locking engagement occurs when the lock is press fitted downwardly over the abutting protrusions on the radially-aligned leg structures. When pressed downwardly, the slot structure edges
224
first penetrate slot structure
218
, and as pressure continues, the lock is frictionally snap-fitted in firm compressive engagement between aligned, coplanar legs whose protrusions occupy the lock slots. The lock comes to rest upon lower ledge
230
. Additionally, each lock comprises radially spaced apart, peripheral notches
240
that are aligned with individual slots
234
(FIG.
22
). In assembly, the lock notches
240
firmly receive and abut arm edges
229
(
FIG. 26
) previously described, to create further frictional locking forces upon assembly.
From the foregoing, it will be seen that this invention is one well adapted to obtain all the ends and objects herein set forth, together with other advantages which are inherent to the structure.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
